Looks like I have resolve it
Knowing that the main relay/fuse circuit backup/ACC under the hood #15 was causing the drain I looked up on https://fusesdiagram.com/honda/fuses-and-relay-honda-odyssey-2003-2008.html.
And found that #15 controls fuses under the dash on driver side 5,6,7,8,9
I then pulled them one at a time and found that back up dropped it 20ma
So I put that fuse back and then tried radio and that dropped it from 70ma to 20ma. And all others didn’t drain anything. Focusing on the radio, I then remembered years ago that a iPod/iPhone aux adaptor had been installed. I then disconnected it and then power draw was 20-30ma when sitting. This is below the 50ma number.
Looks like it’s resolved only time will tell
